▼▼Chapter 6ServerApplicationAny number of client systems can access the measurement data within the database. The presentation of online measurementvalues is dependent upon the number of ports per unit i.e. the client computers directly access the UMGs for online values andfor historical data from the database. The following graphic illustrates this:UMG 507Actual values (online values)GridVis downloadsthe memory data intothe databaseHistoric dataDatabase serverwith GridVisClient computer with GridVisThe UMG 507E, for example, currently has 6 communication ports. Two of these ports are designed as a gateway (port 8000)for downstream RS485 units.The ports can be allocated as follows:Port 1 = database server for downloading the UMG memory by automatic downloadPort 2 = client computer 1 accesses the online values from UMG 507E and UMG 96SPort 3 = client computer 2 accesses the online values from UMG 507E and UMG 96SPort 4 = client computer 3 accesses the online values from UMG 507EPort 5 = BMS (Building management software) accesses the online values from UMG 507EPort 6 = OPC server accesses the online values from UMG 507E197
